An audio apparatus comprises a downmixer (105) generating a downmix audio signal by downmixing a multichannel audio signal. A trained artificial neural network (111) determines scale factors for time frequency intervals of the multichannel audio signal from samples of the multichannel audio signal or the downmix audio signal. A signal generator (113) generates a modified multichannel audio signal by applying the first scale factors to samples of the time frequency intervals and a parameter circuit (115) generates spatial parameters representing relative properties for channels of the first modified multi-channel audio signal. An output circuit (109) generates am encoded audio signal to comprise the downmix audio signal and the spatial parameters. The encoded audio signal may also include a residual signal. A complementary apparatus may receive the encoded audio signal and comprise a trained artificial neural network (111) which from the downmix audio signal can generate corresponding scale factors. An output multichannel audio signal is generated by upmixing the downmix audio signal using these scale factors and the received spatial parameters.

An audio apparatus has a receiver (301) receiving a data signal including encoded data for a mono downmix audio signal and spatial upmix parameters for upmixing the downmix to a stereo signal. It further includes a directional circuit (305) estimating a directional signal of a signal model for a stereo signal, and a generator 317 generating two estimated signals being residual signals of the signal model. A rendering function (307, 309, 311, 313, 319) renders a stereo signal from the signal model. An adapter (321) controls the generator (317) to adapt a relative property, such as specifically a correlation or relative signal level, between the first estimated signal and the second estimated signal in dependence on the spatial upmix parameters.
